Question
Chapter 19.1, Problem 4WDYL
Summary Introduction
To analyze:
About the path that the blood follows through the heart and the two circulations.
Introduction:
The process of blood circulation starts in the chambers of the heart. The pumping action of the heart is dependent on the involuntary cardiac muscles. The exchange of blood between the heart and the other parts of the body takes place through the blood vessels.
